[PATCH 1/1][PPC] replace logical- by bit-and in pci_process_ISA_OF_ranges(), arch/powerpc/kernel/isa-bridge.c

[Roel Kluin]

in arch/powerpc/kernel/isa-bridge.c:
41:#define ISA_SPACE_MASK 0x1
42:#define ISA_SPACE_IO 0x1
...
54:    struct isa_address {
55:             u32 a_hi;
...
65:     const struct isa_range *range;

83:    if ((range->isa_addr.a_hi && ISA_SPACE_MASK) != ISA_SPACE_IO) {
...
89:    if ((range->isa_addr.a_hi && ISA_SPACE_MASK) != ISA_SPACE_IO)

shouldn't these be a single &?
then consider the untested patch below.
--
replace logical "&&" by bit "&" for ISA_SPACE_MASK
